Video based Attendance System

Abstract: Attendance management done manually in college is difficult to work with. To automate the attendance system, there are many technologies available that are costly and you have to touch the pad every time you come to the class which makes it coronavirus prone. Hence, to overcome this problem we have built a computer-based smart video attendance management system. Attendance is an important aspect of every organization or institution to confirm the presence. Some of the manual and automatic attendance systems are, entry by pen or paper, Fingerprint-based, IRIS-based, RFID-based, and face recognition. The possibility of false entry of students by fooling the system is not possible in our case. Our system can take attendance remotely by live video. In this system, all frames are separated from the video. To recognize the face of any student human face detection and pre-conization steps are taken. Our model helps to manage the attendance of students in a live stream. Keywords: Automate, Detecting, Learning, OpenCV, Recognizing, Video.

Unconventional route for performing coronary angiography

We describe herein a 14-year-old patient diagnosed as severe mitral stenosis suitable for balloon mitral valvotomy. A 6 French (Fr) pigtail catheter was introduced retrogradely into the aorta and positioned in the aortic root. An 8 Fr sheath was inserted into the right femoral vein. Under fluoroscopic guidance in the left anterior oblique 40° projection, transseptal puncture was attempted with Brockenbrough needle. As the septum was fleshy and bulging into the right atrium, which was small, it slipped into the right atrium. A second septal puncture was done lower down. A Mullin sheath was gently pushed and left in situ while the needle was withdrawn. Surprisingly, the left anterior descending and circumflex arteries were visualized suggesting coronary angiogram through venous route and when a larger amount of contrast was injected to document the correct entry into the left atrium, false entry into the aorta was confirmed (Figure). Mullins sheath was withdrawn and the patient remained hemodynamically stable. The patient was discharged after the successful surgery. With a conventional transseptal puncture method, serious or even life-threatening complications may occur as perforation of the aorta, pericardium, pulmonary vein, and right atrial free wall, sometimes requiring surgery. Various imaging modalities such as transesophageal and transthoracic echocardiography, intravascular ultrasound, and intracardiac echocardiography may be employed to determine the optimal transseptal puncture site. 224

The role of contrast enhanced transesophageal echocardiography in the diagnosis and in the morphological and functional characterization of acute aortic syndromes

The aim of this study is to evaluate the role of contrast transesophageal echocardiography (cTEE) in the diagnostic characterization of acute aortic syndromes (AAS) [aortic dissection, intramural hematoma, penetrating ulcer]. We enrolled 66 non-consecutive patients with clinical suspicion of AAS. Standard transesophageal echocardiography and cTEE were performed prior to gated-CT angiography, which has been assumed as reference standard. cTEE was obtained with a single bolus of contrast agent injection. The definitive diagnosis of AAS was made in 48 patients by gated-CT angiography: 22 aortic dissections, 15 intramural hematomas and 11 penetrating aortic ulcers. Standard TEE and cTEE correctly diagnosed AAS in 87 and 100% (P = 0.03) cases respectively. Standard TEE correctly diagnosed aortic dissection in 20/22 (91%) and cTEE in 22/22 (100 %) (P = 0.5) cases. cTEE was superior than standard TEE in the visualization of false lumen entry tear (22/22 vs. 16/22, P = 0.03). Standard TEE correctly diagnosed intramural hematoma in 11/15 and cTEE 15/15 (P = 0.12) cases. Microtears were identified in 3 patients by cTEE an in 1 patient by standard TEE (P = 0.4). The presence of focal contrast enhancement was identified in 4 and 0 patients by cTEE and standard TEE respectively (P = 0.06). Both standard and cTEE correctly diagnosed penetrating aortic ulcer in 11/11 (100%) (P = 1.0) cases. cTEE provides additional value over standard TEE in the diagnosis and in the anatomic and functional characterization of AAS.

A profitability study on the Malaysian futures markets using a new adjustable technical analysis indicator, adjustable bands Z-test-statistics' (ABZ')

Financial markets all over the world generally exist in 2 conditions: trending and ranging. One of the most frustrating issues confronting market technicians daily is the critical definition when market is ranging and when the market is trending. Applying a trending algorithm to a ranging market will result in whipsaws that yield losses. To avoid some of these false entry signals, this research proposed to vary the moving average and standard deviation parameters to avoid some of these false entry whipsaws and yet capture a new trend early. Adaptive algorithm like the Adjustable Bands Z-Test-Statistics' (ABZ'), seeked to provide a solution to this issue. For the year 2008, ABZ' showed an abnormal return of 316 index points for Malaysian Kuala Lumpur Composite Index Futures (FKLI) compared with a negative return of -562 index points for the passive buy-and-hold strategy and 690 for Malaysian Crude Palm Oil Futures (FCPO) compared with a negative return of -1387. Results from this research interest investors world wide who are trying to overcome this baffling issue of ranging versus trending markets. Key words: Technical analysis indicators, automatically adjustable algorithm trading systems futures trends.

733 The perfusion score index in the subacute phase as measured with real-time myocardial contrast echocardiography correlates with infarct size in patients with acute myocardial infarction

The usefulness of contrast transthoracic echocardiography (TTE) in aortic dissection has not been validated. With this aim we studied 82 consecutive patients with aortic dissection who underwent contrast TTE and transoesphageal echo (TOE). The results were compared with those obtained by or CT. Results: Contrast TTE diagnosed entry tear located in distal ascending aorta and aortic arch in 29 cases. TOE suspected only 8 of these. Contrast TTE defined false lumen entry flow severity in all cases and permitted the assessment of proximal descending aorta but was limited for distal thoracic aorta. In abdominal aorta, contrast TTE facilitated the diagnosis of false lumen drainage and distal re-entry tears. Comparison of proximal and distal descending aorta contrast pattern was very useful for understanding false lumen flow hemokinetics and pressures. Conclusion: Contrast transthoracic echocardiography is highly useful in assessment of aortic dissection, particularly in the upper third of ascending aorta, arch and abdominal aorta. Overall assessment of false lumen flow kinetics with contrast provides information that may be significant for improving management of this disorder.

A duty of candour: will it really make amends?

The junior doctor lied. He made a false entry in the medical record of the woman he had seen to conceal his obvious negligence, and then made a false statement during the investigation which followed her serious complaint. The distress and indignation of the client was understandable. It is her word against his. After obtaining all the details and listening to the account of the woman, who had professional qualifications herself and had no reason to lie, we have no doubt which one we believe.

Allied Irish Bank — Lessons to Be Learned

AIB Group released the following statement on 5 June in response to the announcement by the US Attorney’s Office in Maryland that John Rusnak be indicted on charges of bank fraud and false entry in bank records. “AIB Group and Allfirst welcome the Grand Jury’s decision to indict former employee John Rusnak on charges of bank fraud and false entry in bank records. AIB stated at the outset that it believed it was the victim of a complex and sophisticated fraud and these charges endorse that conclusion.”

Asymptomatic endometrial polyps in postmenopausal women: are they an indication for surgical removal?

Purpose: To compare demographic, sonographic, and outcome data of postmenopausal patients with asymptomatic endometrial polyp, surgically treated or not treated.Methods: Ninety postmenopausal women with sonographic/sonohysterographic diagnosis of asymptomatic endometrial polyp were prospectively enrolled in this study. All patients underwent transvaginal sonography with color Doppler evaluation (Voluson 5300, KRETZ), and sonohysterography in selected cases. Patients were counseled on the risk of malignancy (estimated risk < 1/200). Sonographic follow up at 3, 6 and 12 months was proposed as an option to standard hysteroscopic polipectomy. Surgery was considered in case of bleeding, polyp enlargement, or Doppler PI < 0.6. Demographic and sonographic data of both groups were recorded. Surgical complications in group B patients were considered as abnormal outcome.Results: Sonographic follow up was chosen by 42 women (group A) and surgical removal by 47 patients (group B). Forty‐three patients underwent operative hysteroscopy, and four patients hysterectomy (group B). One major (uterine perforation not requiring surgery) and three minor complications (two cervical lacerations requiring hemostatic suturing, one false entry) (9%). Demographic (age, years of menopause, blood hypertension/diabetes, BMI, nulligravidity, hormonal replacement therapy assumption, tamoxifen assumption) and sonographic data) Endometrial thickness mean (interquartile range) = 8 (5–10) vs. 11 mm (7–13); volume (cc): 3 (1–4) vs. 4 (1–5); PI: 0.48 (0.44–0.51) vs. 0.49 (0.45–0.53) were not significantly different between group A and B. Pathologic findings were glandulocystic and hyperplastic polyp in 45 and in two patients, respectively. All group A patients remained asymptomatic in the follow up period (mean 10 months, interquartile range 5–16).Conclusions: Demographic and sonographic data were not significantly different in the two groups. No untreated patient became symptomatic during follow up period. Benign lesions only were found in treated patients, at the cost of one uterine perforation. A large multicentre study is needed to understand the exact prevalence of endometrial cancer in asymptomatic endometrial polyp, and verify the safety of conservative management.

Modern diagnostic concepts in dissection and aortic occlusion

For the diagnostic work-up of the aorta, non-invasive cross-sectional imaging techniques have almost replaced invasive catheter angiography. CT- and MR-angiography are supplemented by sonography which is used predominantly for the assessment of abdominal aortic aneurysm and dissections of the thoracic aorta. This review deals with the diagnostic approach to two disease entities involving the aorta: aortic dissection and aortic occlusion. Transoesophageal echocardiography (TEE), CT- and MR-angiography (MRA) are used in the assessment of aortic dissection. Published sensitivity and specificity values regarding the detection and classification of dissections into Stanford A and Stanford B range between 96-100% for all three modalities. Results for multislice CTA have not yet been reported, but can be expected to be at least as good. The ability to delineate additional information regarding the precise morphology of true and false lumen, entry and reentry-sites, the development of thrombus or paraaortic hematomas, as well as the assessment of aortic regurgitation or involvement of coronary arteries depend on the chosen technique. Reflecting the ability to collect functional imaging data, both TEE and MRA are superior to CTA in the assessment of aortic valve involvement, while TEE is the modality of choice for evaluation of coronary arteries. Sonography is of limited use in the assessment of abdominal dissections. For the evaluation of patients with suspected aortic occlusion both CTA and MRA represent the imaging modalities of choice. Both provide for a comprehensive and precise depiction of the underlying aortic morphology, the extent of collateral flow as well as delineation of distal run-off vessels. MRA should be employed in patients with impaired renal function as paramagnetic contrast agents are not nephrotoxic.

Improved frame synchronization performance for CCITT algorithms using bit erasures

For the CCITT recommendations on frame synchronization (as enhanced in Jones and Al-Subbagh, 1985), the performance in the presence of jamming, interference or other disturbance is improved by using bit erasure information. The acquisition time and misalignment detection times are reduced and the false exit time is increased, with only a minor reduction in the already large false entry time. >

Algorithms for frame alignment — some comparisons

The paper presents a comprehensive analysis of frame alignment strategies for time division multiplexed digital signals. Comparisons are made between algorthims recommended by CCITT and others requiring slightly more sophisticated terminal processing. The principal transition times (misalignment detection, false exit, acquisition and false entry times) form the basis for comparison. The enhanced algorithms are shown to be better able to handle the conflicting requirements of rapid misalignment detection and the need to maintain an aligned condition in the presence of transmission errors. They also result in a significant reduction in acquisition time at high error probabilities, the condition under which alignment equipment is often required to act.

Internal Comparison of a Large Group of Standard Cells

Equipment is described for comparing any number N of standard cells which constitute a standard of electromotive force. The scheme is economical, needing only 2N measurements. The cells are disposed in a ring, and there is simple switching to compare each cell with its four neighbors. The calculations are done by a program on a desk calculator. They give the value of each cell with respect to the mean of the group. They also give the rms error, which is typically less than 0.02 ?V for one cell in a group of 22. There are safeguards for identifying a spurious measurement and a false keyboard entry.
